Patent DE-2415916-A1 (DE)
Title: Two component plastics mixed in constant ratio - but with varied feed rates through fishtail dies into chamber
Inventor: MAHLMEISTER GUENTER
IPC: B29B7/76
Filed: 1974-03-29
Abstract: A method of producing a chemically reacting mixt. from two liquid plastics components supplied in different quantities is carried out in a mixing chamber having two separate inlets for the components and a common outlet; the two components are fed into the chamber through opposite fishtail dies having rectangular cross-sections proportional in their area to the ratio of the components to be mixed; a regulating slide valve obturates these two dies in the same proportion so that during tne entire opening and closing operation of the dies a constant mixing ratio is maintained. An accurate mixing ratio is maintained, since at no times does one of the components predominate over the other, for example in an access duct. The two dies are of rectangular cross-section, having the same width (longitudinal dimension) but having different depths to suit the mixing ratio. They are mounted at opposite walls of the chamber so that the two ends of on die lie opposite to the corresponding ends of the opposite die across planes transverse to the chambers longitudinal axis.

Title: Air conditioning system for operating theatres - supplies air through plenum box with perforated base and primary jets
Inventor: PASSAU ROBERT ING GRAD
IPC: F24F13/068
Filed: 1974-12-07
Abstract: Conditioned air is supplied through a ceiling mounted plenum box (1) which has a rectangular c asing (2) and a base (3) constructed from a number of perforated plates.

Title: Monitoring circuit for vehicle exhaust catalyst - has warning light operated service life via relay actuated by counter
Inventor: SCHREINER HERMANN
IPC: F01N11/00
Filed: 1974-12-12
Abstract: The monitoring circuit employs a counter mechanism with a rotating digital drum (4) having a notch at a given point around its circumference, so cooperating with a switch (5) that the latter is closed, when the service life of the exhaust catalyst expires. The closure of the switch causes the destruction of a fine fuse (6), which in turn causes a relay (7), for energising the warning light (3), to operate. Preferably the counter mechanism is the odometer incorporated in the speedometer of the vehicle. The warning light may be connected across the vehicle battery (1) via the ignition switch (2).

On this occurring the lifting device (6) is driven at reduced speed or stopped, thus maintaining a driving torque greater than the overload torque. A timer delays the switching off of the drive after the occurrence of the overload. It can be switched on again (7) after a further time delay, and in between the mechanism can be arranged to make a small movement in the reverse direction.

Title: Hydraulic braking and damping attachment for valves - eliminates water hammer initiated by feed-water changeover valves using piston with restricted bore
Inventor: NOVAK WALTER DIPL ING
IPC: F16K31/122
Filed: 1975-03-10
Abstract: The equipment is mounted on top of the valve and its spindle is coupled to that of the valve. It comprises a double-acting hydraulic cylinder. When the piston and valve are in the upper position and are actuated downwards, fluid is forced from the lower chamber into a drilling in the spindle, through a throttle tube and out through another hole in the spindle into the upper chamber, the pressure difference across the throttle tube producing constant speed movement. After a predetermined travel, the port is closed and entry is via drillings in the piston from which the fluid flows through a second throttle tube before reaching the first, thus reducing the valve closing velocity. An alternative simpler design utilises a single throttle tube.
